For those who don't know, different yrs of the Yz125's have different gear ratios. My 99 Yz125 only has 5 gears. My 03 Yz85 has 6 gears and runs circles around my 125. However, my yz125 does have more torque, but that means nothing in a bike race. My 125 tops out at 64mph and my 85 tops out at 73mph. Now, had that dude's yz125 been an 02 or newer, the 85 probably would've been eaten alive. The 85 came out in late 02 so, if its not a bike around that year, the 85 is more than likely gonna blow it out of the water. Its truly a state of the art bike.
I never gonna understand how those 85 can produce more power sometimes than a 125 i mean i see some out there and they’re mean compared to a 125 love the 125 to. I do own a kx250 because i weight 240 pounds but if i was skinnier i will own a 125 or even a 85 theyre look super fun and for some reason i love more the sound of those little engines🔥
@@trailridersandfun5798 there’s no replacement for displacement and just because a bike has 5 gears vs 6 doesn’t make it slower. The key is gear ratios.
Well 85s also have the faster acceleration then the 125 the 125 is gonna have the faster too speed but the 85 is got the more power band kick and acceleration i speak from experience with havin a 85 and racing a 125
That all depends on the year of the bike! My 2003 Yz85 tops out at 73mph & my 1999 Yz125 tops out at 64mph! A 2003 Yz125 vs a 2003 Yz85, YES. The 125 will win everytime.
85 and 125 have the same acceleration because the bike has the same power/weight ratio. The same acceleration provided the pilot does not exceed 130lbs for the 85 and 170lbs for the 125.
I'm a 13 year old and I've had a test ride on a yz250x and a wr450 and that 450 has heaps of power, and isnt as much fun as the 250x, stick with 2 stroke, way better than 4 stroke
Owen Smith I wish I woulda followed that!! I knew how to use a clutch from my 4-wheeler but then I jumped straight to a yz125! The first 2 days were hell and not fun, but I'm finally getting to the point where I'm doing good and it's becoming really fun
yes its my first dirt bike.. my brother and I bought it together and he is 20 so we had to buy something strong. but i was riding a lot of 85 before and 85 is too small and not powerfull enough for me
Caleb Guidroz yz85's fly they can go 100 if u have a long enough straight and if u are going hard out because a yz125 goes way over 100 i think it goes 140
jonnyhotpants 125 is better all around but a 85 is a million times funnier just throw a big boar on it!!! Just remember there is no fun in throwing a big bike around!!! I'm 5'11" and I have more fun on a pit bike then my 125
I remember watching this video shortly after it was uploaded, crazy it's been 6 years

OG god, also he commented 1 year ago. So 6…
@@huntermalone6883 I can’t believe it’s been a year since I made that comment. Could’ve sworn it was a couple months ago lol
Thanks to the algorythm

Beautiful
Another thing to note (1 yr later) 🤣 the yz85 weighs nothing! All that top end & no weight makes the front wheel come off the ground in EVERY gear!
I never gonna understand how those 85 can produce more power sometimes than a 125 i mean i see some out there and they’re mean compared to a 125 love the 125 to.

Ur 85 does in its Bollox do 73mph 🤣🤣🤣
125 should have demolished that 85, it didn't sound right either
Powervalve must be stuck or something
Better drivers help a lot. The 85 got a better start and shifted better.
Well 85s also have the faster acceleration then the 125 the 125 is gonna have the faster too speed but the 85 is got the more power band kick and acceleration i speak from experience with havin a 85 and racing a 125
bro everybody says that but every video the 85 wins so maybe ur wrong buddy
125 and 85 prolly had different gear ratios
Every YZ 85 is always beating a YZ 125 on UA-cam. Its all in the rider.
Yea they always change the riders so the odds get a evened out.
Fact
true I like yz 85 no big wheel
Yes it's in the rider really.
125s seem as powerful as 85s but louder
if you ride both bikes right, the 125 Will easly leave the 85
Dude the 125 has way more power, a 125 will beat an 85 anyday with a good rider.
That all depends on the year of the bike! My 2003 Yz85 tops out at 73mph & my 1999 Yz125 tops out at 64mph! A 2003 Yz125 vs a 2003 Yz85, YES. The 125 will win everytime.
You got to think, that 125 may only have 5 gears like mine. That 85 has 6! Plus, its almost the same engine but on a WAY smaller frame.
I also am running a casted piston on my 85 (way lighter than forged, makes it meaner) but is not as durable as forged piston.
Miss my yz 85
Is it very short off of a 250? ( height wise ) 250 4 stroke
I miss mine too, I owned it when this video was first uploaded. It was a fun bike, got a 2015 rmz 450 now
That 85 looks really tall
wheel to big
85 and 125 have the same acceleration because the bike has the same power/weight ratio.
The same acceleration provided the pilot does not exceed 130lbs for the 85 and 170lbs for the 125.
I have a ktm 125 2015. And I'm 13 years old. Do u think I should get a 250 or 450. Because I can handle my dads 250
Jason Pearce 😂😂😂😂
Jason Pearce 😂😂😂😂more power doesn't make you a better rider pluse stick with 2 strokes they are cheaper and lighter
Jason Pearce first of all sell ur ktm and buy a Yamaha 250, lmao
I'm a 13 year old and I've had a test ride on a yz250x and a wr450 and that 450 has heaps of power, and isnt as much fun as the 250x, stick with 2 stroke, way better than 4 stroke
If i should have my first bike would a Yamaha 125 ttr from 2007 be good?
I am 6´0 and 150 lbs.
Or do you guys have another idea?
Yz 125
The one riding just scared to get on that throttle
I never rode a dirt bike, I'm 5'9 and 120lbs, u guys think yz85 good to begin with, or go straight to the 125?
Davyd Bosyuk 85 for sure
Straight to the 125
A m2r 140 would be good or a klx 125
Get a ttr 230 or crf230 dont get a 2 stroke untill u know how to ride
Owen Smith I wish I woulda followed that!! I knew how to use a clutch from my 4-wheeler but then I jumped straight to a yz125! The first 2 days were hell and not fun, but I'm finally getting to the point where I'm doing good and it's becoming really fun
Noway 70-100
i am 172cm tall or 5'8 am i too big for yz 85 should i get with big wheels or small ones
Thank You!
You need a 125 not a 85. I'm 5'8 and ride a kx 125 easily and I had a YZ 85 before I got my 125 your way too big for it.
Yeah 125 but you'll get a shock of how high it is and crazy fast for a 125
you need a 250 2 stroke im 16 yo and around 170cm tall and i can easily handle it
but was a 250 your first bike or ?
yes its my first dirt bike.. my brother and I bought it together and he is 20 so we had to buy something strong. but i was riding a lot of 85 before and 85 is too small and not powerfull enough for me
💪🏻👍🏻
We High are you
Eyah
Caleb Guidroz yz85's fly they can go 100 if u have a long enough straight and if u are going hard out because a yz125 goes way over 100 i think it goes 140
You're funny :) I love trolls
theperson185 kmh, mph anyone
My yz125 does exactly 100kmh or 62 mph, but I'm not sure if it's stock gearing
+theperson185 I thought they do 78 standard?
Should I get a yz85 or 125 I'm about 5 4 my friend has an 85 but never rode a 125
jonnyhotpants 125 is better all around but a 85 is a million times funnier just throw a big boar on it!!! Just remember there is no fun in throwing a big bike around!!! I'm 5'11" and I have more fun on a pit bike then my 125
jonnyhotpants im 12 5.7 a beginner am i good for this bike ? please repond
jurcek 000 yes
Guilty. 5’4 here love my 85sw perfect seat height
Wich one is the yz85 and the yz125
125 is the far one
@@zane4964 no in thos 85 somoked a 125
Will i fit on a yz85 if im 5'7 and 140 pounds
get a 125 or a 250
The yz is to small?
Yeah easily I'm the roughly the same height and fit a yz 125
+ENDURO SK I agree, depending on your experience
I think you’re on the edge of that bike size, the 85 big wheel would be fine but you’ll upgrade later in the future I rekn
I’m 6.1 should I get a 125
Bailey_ _15 get a 50
Sx 5 mini
Yes...!!!!!!!!!
sub-125's are for young boys, young short teens , young chicks, and dwarfs! :)
Mate they fly
Both these guys don't know how and when to shift gear on a 2t
I'm wanting a yz85 but I don't now there top speed anyone now
Some where around 60 to 70 it depends on ur weight
60-80 if you are in the bikes suggested requirements no way it goes 100
Ya my friend weighs bout 145 and he's got a 2-stroke rm85 and he gets it up to 80 sometimes but they will beat most yz85s
You're stupid, and 85 will not do 80. My YZ125 kills every single 85 I go against and I'm doing 78
I have an 07 85 and my friend and I drag raced and we toped out at around 60 - 65 mph. My friend has an xr250 and I won the drag race btw.
jonnyhotpants get a85cc way better
Not much difference
